Bongo Fury

Hi (hope this image uploading palaver works!)

Found this box dangling down in the drivers footwell of our newly aquired Bongo just above the accelerator. Writing is in English so looks aftermarket "Com?? Master??" I've tucked it away safely but would like to know what on earth it is! I suppose I could just disconnect it and see what stops working but probably safer to ask here first! Any ideas?

Looks like the faded writing actually said 'Combi Master' and it's a split charge relay for the Leisure battery (Thanks Richard from FB)

Well done.
